Abstract: | The application of field effect transistor (FET) detectors integrated with planar twin dipole microstrip antennas to millimeter-wave imaging has been demonstrated. Circuits were configured as practical heterodyne mixers, as elements in a 2×3 element planar focal plane array for imaging, and as receivers in frequency modulated (FM) radars for three-dimensional imaging, at 63 GHz. These experiments show that quasioptical circuits, using conventional present-day FETs and simple printed circuit construction, can be applied usefully in the millimeter-wave region. |
